Parasitism of dolfinfhishes, <i>Coryphaena hippurus</i> and <i>Coryphaena equiselis</i>, in the western Mediterranean (Balearic Islands) and central-eastern Atlantic (Canary Islands)

A total of 648 dolphinfishes were examined for internal and external parasites in western Mediterranean (Balearic Islands) and central-eastern Atlantic (Canary Islands) waters in order to make a comparative study between the two areas. The specimens studied from the Mediterranean Sea was Coryphaena hippurus, with 62 large individuals captured from May to September and 497 juveniles captured from August to December. The specimens studied from the central-eastern Atlantic were 39 adult C. hippurus and 49 adult Coryphaena equiselis. Parasites were found in 70% of the fish examined, and represented a total of nine endoparasitic taxa: six digeneans (Class Trematoda, Subclass Digenea; Dinurus tor…

Social Intervention in Traffic Safety

Traffic accidents during the transport of merchandise or passengers on roads and highways have, from the beginning, taken by surprise those who have experienced them themselves or involving persons close to them, as well as those who have witnessed accidents or, in one way or another, helped to alleviate their effects. They say that Albert Einstein commented after the death of a friend: “The worst thing is not only the fact that traffic accidents occur, but also how little we know about why they happen and how little we do to prevent them...”

Osteonecrosis of the jaws by intravenous bisphosphonates and osteoradionecrosis : a comparative study

Aims: We analyze the possible clinical differences between bone jaw exposed areas in ONJ (osteonecrosis of the jaws) and ORN (osteoradionecrosis). Patients and method: Group 1 was composed with 53 ONJ cases and group 2 with 20 ORN cases. In both groups we analyzed, the major size of the exposed bone areas, the number of exposed areas, the location on the jaws and the presence of others associated and severe complications, such as skin fistulas and jaw fractures. We also investigated the possible local aetiology or trigger factor of the lesions. Results: The major size of the bone exposed areas was 2.29±2.02(mean ± std.dev) in group 1 and 2.7±2.9 (mean ± std.dev) in group 2 (p>0.05). The num…

Temporomandibular disorders : a case-control study

Objective: To compare the risk factors and clinical manifestations of patients with temporomandibular disorders (TMDs) diagnosed according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) (axis I) versus an age and gender matched control group. Study Design: A total of 162 patients explored according to the RDC/TMD (mean age 40.6±18.8 years, range 7-90; 11.1% males and 88.9% females) were compared with 119 controls, measuring differences in TMD risk factors (sleep disturbances, stress, psychoactive medication, parafunctions, loss of posterior support, ligament hyperlaxity) and clinical variables (joint sounds, painful muscle and joint palpation, maximum aperture…

Looking for skin and gill parasites as biological tags for Atlantic bluefin tuna (Thunnus thynnus)

Skin and gill parasites found in juvenile Atlantic bluefin tuna (Thunnus thynnus) caught in the Bay of Biscay, northeast Atlantic, were examined with the aim of finding biological tags. The degree of infection of different microhabitats was analyzed and the annual prevalence by species of parasite obtained. Of the specimens examined, 98% had parasites, and the gills were by far the most infected microhabitat, followed by the skin and the pectoral fin. Within the gill cavity, parasites were most commonly found in the afferent margins of the primary lamellae. Three species of Copepoda were identified, two species of Monogenea, and eleven Digenea. Thus, ten species (Digenea: Didymozoidae) and …

Insular stock identification of <EM>Serranus atricauda</EM> (Pisces: Serranidae) through the presence of <EM>Ceratothoa steindachneri</EM> (Isopoda, Cymothoidae) and <EM>Pentacapsula cutanea</EM> (Myxozoa, Pentacapsulidae) in the Canary Islands

Ceratothoa steindachneri (Isopoda: Cymothoidae) and Pentacapsula cutanea (Myxozoa: Pentacapsulidae) parasites infecting the blacktail-comber ( Serranus atricauda ) were considered suitable as biological tags for stock identification around the islands of La Palma and Gran Canaria, in the Western and Eastern areas of the Canarian archipelago, respectively. The ecological parameters of both species differed significantly between the islands. While individuals caught off La Palma showed a high degree of infection by the isopod, a single infected fish was found off Gran Canaria. Also, the myxozoans showed a high level of infection on fish from Gran Canaria but it was reported on only a single s…

Multiple online victimization of Spanish adolescents: Results from a community sample.

Little is known about online victimization of Spanish adolescents. The present study aims to determine the past-year prevalence of online victimization in a community sample of Spanish adolescents. The final sample consisted of 3,897 adolescents between 12 and 17 years old (M=14.45, SD=1.59), 1,836 males and 2,049 females, recruited from 39 secondary schools in the east of Spain. The Cuestionario de victimizacion juvenil mediante internet y/o telefono movil (hereinafter, Juvenile Online Victimization Questionnaire, JOV-Q, Montiel & Carbonell, 2012) was applied for the assessment of eight types of online victimization grouped in two major domains: sexual (sexual coercion, sexual pressure, on…
